NJT VAT Return Demo (MTD) - Version 7.3 released on 6th August 2022

(This free software simulates the submission of VAT Returns for businesses & agents, it does not actually communicate with HMRC)

The free 'NJT VAT Return Demo (MTD)' is a separate software product that simulates the live 'NJT VAT Return Manager (MTD)' software product.
For information, before you can use the 'Live' software product, you first need to sign up to MTD. This is because the first step is to 'Grant Authority' using your MTD VAT account.
Consequently, it is difficult to obtain a practical understanding of how the 'Live' software works. This is where the demonstration software may help to improve knowledge and awareness.

The demonstration software allows you to simulate the full 'End to End' process without being signed up to MTD. This is a perfectly safe method to familiarise yourself with the functionality of the 'Live' software' without actually communicating with HMRC. Additionally, you may wish to use this software to assist in training or to improve understanding of the required processes under MTD.

All you need to use this software, is a valid VAT Registration Number and the ability to create VAT returns in any of the formats supported by the software.
For information, you can also 'Reset' the demonstration software, via the 'Administration Routines', and repeat the processes as many times as you wish.

Please Note: The 'Demo' and 'Live' software are different products. If you wish to purchase the 'Live' software, then click on the menu item 'VAT Return Manager (MTD)' and follow the instructions within the 'Software Purchase & Renewal' section.


The software is compatible with Microsoft Windows and Microsoft Excel.
The software is Not compatible with Apple Mac Computers, OpenOffice or LibreOffice.

How to install the 'NJT VAT Return Demo (MTD)'
  1. Create New Folder
    Create a new folder on your computer. For example, "C:\My Demo".

    Tip: You may wish to create a shortcut on your Windows Desktop, which points to this folder. Note: The actual file name of the software will change when subsequent versions are released, so the shortcut needs to point to the Folder and not the file.

  2. Change Excel Configuration (Options/Trust Centre)
    Microsoft has taken a much tighter approach to software security. As a result of this, some Excel features are disabled during initial installation. In order for the VAT Return Demo to function correctly, a few changes are required within the Excel Options.
    Open a blank workbook in Excel. (For recent versions of Excel, Click on 'File' menu, then 'Options', then 'Trust Centre' then click on 'Trust Centre Settings').
    Note: For Office 2007, Click on the 'Office' button as the 'File' menu does not exist.
    1. Trusted Locations: Add the 'Location' of the folder where you saved the workbook,
      (For example, "C:\My Demo"). Also tick the box 'Subfolders'.
    2. Macro Settings: Tick the box 'Trust Access to the VBA project model'.
    3. Then, click on the 'OK' button.
    4. Finally, Exit Excel.
